Specification of Letters Patent.

Patented Jan. 28, 1919.

Application filed August 26, 1918. Serial No. 251,546.

To all whom it may concern:

Be it known that I, ARTHUR MUSKER, a subject of the King of England,residing at London, in the county of Middlesex, England, have inventednew and useful Improvements in or Connected With the Discharge of Cargoin Bulk from Barges or Vessels and the Delivery Thereof, of which thefollowing is a specification.

This invention has reference to systems of the discharging or removal ofcoal, ore, grain or like cargo in bulk from barges or vessels, and theelevation and delivery thereof.

In the specification of my previous application for patent filed Feb.12th, 1918, Serial No. 216,808 a system of discharging coal, etc., inbulk from barges or vessels, and the elevation and delivery thereof isdescribed, in which a floating pontoon carrying operating machinery isused, and placed when operating, end on to the barge or vessel to bedischarged. While this system is very advantageous, in some cases 1t isdesirable that the space longitudinally taken up alongside a ship, whichis to receive the goods, and between it and a quay, should be as smallas possible; and the present 1nvention has for one of its objects andeffects to provide a system and arrangement by which the said space isrendered less than is necessary in operating according to the system ofthe aforesaid invention.

In the present system the space taken up,

is only that taken up by the barge or barges, which will be between theside of the ship to receive the coal or goods, and the quay, from whichitthe ship-is breasted off.

The system of and means for discharging or removal of coal or grain orlike cargo 1n bulk from the barges or vessels, and the elevation anddelivery thereof, will be described with the aid of the accompanyingdrawings which illustrate same.

leys 6 being provided on the outer end of the boom, over which theoperating chains or ropes 7 a bucket 3, pass. The boom is carried by amast 20, to which it is pivoted at 17, and the part of the chain 7 whichis paid on to and oil the operating machinery passes over the boompulley 6, and pulleys l4 and 15 fixed on the upper end of the mast. Thechain 7, together with the chain 8, after passing about pulleys 14 and15, pass down to operating machinery which is preferably placed on thebarge or pontoon 10*.

The pull rope 8 connected with the bucket is carried over similarpulleys 14, 15, so that by means of the operating engine or windingmachinery, these ropes or chains 7 and 8, are operated, and the bucketmoved over and into the barge or vessel 2 containing the material to bedischarged, and to be delivered into the ship 1; and after the bucket islowered into the barge 2, and has filled itself in the well known way,the gear or tackle is so operated that it will be moved up into aposition vertically over the hopper 5* on the mast 20, which isvertically adjustable on it; and when the bucket is discharged into thishopper 5 the material is delivered by a chute 16 on it into a hatch 13on the deck of the ship 1, after which it is again moved and loweredinto the barge or vessel 2, and the operation is repeated.

In some cases two sets of tackle or buckets can be used, one on eachside of the mast 20 and boom 4, which, as shown in Fig. 2, has a crossbeam 4 at the outer end, so that by one set of machinery, two bucketscan be operated on the one vessel 10*.

The boom 4 is adapted to be raised by tackle 18 and held up against themast 20 when not required for operating.

This invention thus, while being one entailing relatively a low firstcost of machinery, enables material to be, discharged from barges orvessels in different positions; and provides an elevator system in whichthe first cost of the elevator would be low.

Regarding the mast 20 of the pontoon 10*, it may be mounted on a pivot19, in the form of a post fixed on the pontoon, upon which it canrevolve, and thereby afi'ord greater range of movement of the grabbucket and delivery from the chutes 16 connected with the hoppers 5".

In discharging material from barges by the system above described, inwhich the operating machinery is carried on a pontoon, it is importantthat the movement of this pontoon in the water, when the bucket is beinglifted, should be as small as possible; and movement in this respect isprevented by the movement of an engaging and freeing means between themachinery pontoon and the barge from which material is to be taken,which is adapted to temporarily hold the two together at this time, sothat the pontoon will not rise or sink in the water except when thebarge rises or sinks; but when the bucket is not being lifted, the saidmeans would allow the barge to rise as the material was discharged. Bythis means greater stability would be given the pontoon as the buoyancyor weight of the barge would be added to it at the time when they areengaged.

One method of carrying this out, is illustrated in the Figs. 3 and 1,whereby the pull of the grab or gear when the grab is being raised, dueto the angle of the pull or operating rope, such as exists in Fig. 3, isadapted to put the holding means into engagement, while when this pullis off, the buoyancy of the barge would affect disengagement of themeans, and allow the barge to rise.

In this device, there is employed a rack 21 on a post 22 on the pontoon10*, having \l-shaped teeth as shown, and a corresponding claw 23 orshort rack with similar teeth, on the barge 2, so that when the bargeand pontoon are pulled together in the manner described, the engaging orholding is effected, while when the barge is not being pulled to thepontoon, the claw or rack 23 frees itself, and so allows the barge torise The claw 23 is suspended by a chain 8.

The rack 21 has outwardly projecting flanges 24 forming a channel withinwhich lugs 25 on the claw 23 fit and work,which keep the two partstogether within limits; and springs 26 are provided between the rackpart 21, and the short rack or claw 23, and normally press them apart,so that the teeth of the two parts are free of one another when thebarge is not pulled toward the pontoon.

A modification of the mode of operating tackle of the character referredto is illustrated in Fig. 6.

In this case, the pulling of the bucket or tub 3 from a position overthe barge to be discharged to a place of delivery, say a hopper carriedby the mast 20 on the vessel 10*, similarly as shown in Fig. 2, iseffected by the bucket lifting or actuating rope or chain, or ropes orchains 7, which in the present case pass over a pulley block 11 carriedfrom a slack endless movable rope or chain 8*, which passes over apulley 6 on the boom 4, and a pulley 6* on the upper end of the mast 20.The ropes or chains 7 pass over pulleys 15 on the mast head to a windingand actuating machine 9, driven say by an electric motor.

The endless rope 8 may pass twice around the pulley 6", which would befitted with a brake or clutch, so that by working this brake or clutchthe wheel 6 can be held and released, and the pulley block 11 can. beheld in any desired position in relation to the mast at the momentsrequired.

In working, the pulley block 11 will be moved to a position so that thegrab or bucket 3 when lowered comes onto the material in the barge orvessel 2; and when the bucket or grab is so lowered the closing andlifting ropes or chains 7 will be operated by the machinery 9, and thebucket is raised until it comes in contact with the block 11*, whereuponthe wheel 6 or rope 8 is released by removing the brake or clutch fromthis wheel 6*, and under this condition, the block 11 will be movedupward and inward toward the mast laterally; and when it is to therequired level and position over a hopper which it will be assumed iscarried on the mast, the bucket would be discharged into the hoppersimilarly as above described with reference to Fig. 2. Then afterward toreload, the block 11 is run out and down (either by its own weight orspecial weight connected with it, or by mechanical power if desired) andwhen the desired position is reached, the wheel 6 is again locked by theclutch or brake, and the operation is repeated.

In the case of a tackle of the kind referred to being used to dischargebarges, which would be end-on to the machinery barge 10*, instead of atthe side as shown in Fig. 5, to allow for varying distances between thepulley equivalent to 6, which would be on the end of the barge farthestfrom the vessel 10*, and over which the chain or rope 8 would pass, thisrope or chain 8 would be carried beyond the pulley 6 and passed over asliding weighted pulley 30, which would be suiliciently heavy to holdthe rope slightly slack when the weight of the grab with its materialwas being lifted.

This weight 30 would rise and fall as the distance between the pulleysvaried.

While several modified modes of the system or method herein described ofmoving the bucket or the like transversely across the barge, as well aselevating and lowering it, have been described and shown; yet theinvention may be carried out by different arrangements of such tackleand ropes, so long as the transverse movement by a pulling action, andthe raising and lowering by the tackle and ropes, is effected.
